Abort shape deletion

[dani]

Hi there,

I'm building a database-editor with Visio.
I want to check whenever a user deletes a shape (catch the
BeforeShapeDelete event), if the shape may be deleted or not.
If not, the delete operation should be canceled.

thanx for help

Daniel

Hi Dani

I propose you, to use "QueryCancelSelectionDelete"-Event.
This event fires, bevore ShapeDelete is executed.
You can evaluate the returned boolean value to stop Shape deletion.

BeforeShapeDelete is not used for aborting a deletion. It is used to collect
information from the shape(s) before they are deleted so that other actions,
like deleting associated shapes, can be performed.

Once you get to BeforeShapeDelete, you are commited to deletion.

Follow Peter's suggestion.
